After some much-needed rain Tuesday and Wednesday, we get a day to dry out on Thanksgiving. Expect plenty of sunshine for much of the day (albeit with clouds increasing late) and some cooler and drier air as well — we’ll wake up to lows in the mid-40s that will yield to highs in the low 60s as generally light north winds blow in. Overall, it looks like a great day to get together with family for food and football, amongst other things.
A cold front will continue to approach the area overnight Tuesday into Wednesday, bringing a line of showers and a few thunderstorms along with it that’ll arrive Wednesday morning. Some periods of heavy rain may be possible, and even a couple pockets of gusty winds won’t be out of the question, either. It’ll be one more warm and muggy start with lows bottoming out in the mid-60s. Highs head to the low 70s in the afternoon ahead of the front, which should get through late Wednesday. Once this happens, cooler and drier air will push in, and we’ll wake up to temperatures in the mid-40s on Thanksgiving Day. High temperatures will only reach the low 60s with continued cool advection under partly cloudy skies. Shower chances return on Black Friday as another disturbance moves across, but it won’t be quite as potent and rain shouldn’t be nearly as heavy, nor will it be a total washout. Expect generally similar temperatures to Thursday, so you’ll probably want longer sleeves with a bit of a water-resistant flair to them.
Tuesday’s forecast will be unsettled at times with periods of showers ahead of a cold front that’ll advance through the area on Wednesday. It’s going to be a warm and humid day, with lows around 60-61° warming to the mid-70s in the afternoon. Shower chances will increase as we get into Tuesday night and early Wednesday, and some rumbles of thunder may be possible as well. We need the rain and it looks like we could get a fair bit of it in spots. A half-inch of rain seems to be a decent bet in many locations, with locally heavier amounts possible as well.
We have a relatively mild Thanksgiving Day ahead as temperatures start in the mid-50s, about 10° above normal for this point in the year. Pesky cloud cover will remain pesky with the coastal trough lingering offshore, and a few showers will be possible before rain chances increase further after sunset as more moisture makes its way ashore. Overall, don’t be surprised to dodge a shower or two, but I suspect that a lot of us get a majority of Thanksgiving in rain-free.
Friday & the weekend: Periods of showers with a nice day in the middle
Shower chances will peak on Friday as a warm front moves by followed by a cold front moving in from the north overnight. Lows will approach 15° above normal with cloud cover and a moist airmass in place. The warm front will help temperatures reach the low 70s in the afternoon despite shower activity that’s expected to be in the area. (A thunderstorm can’t be ruled out, either.) These showers will work their way out of here overnight with the aforementioned cold frontal passage.
Saturday should remain mostly dry with a mix of clouds and sun remaining in place. Temperatures will once again bottom out around 10°+ degrees above normal for another mild start followed by highs running right around 70° in the afternoon.
Showers return to the forecast Sunday as another cold front moves by the area. Once again, highs in the low 70s will follow a seasonably mild start to the day in the mid-50s. We should see showers begin to decrease later in the afternoon, paving the way for a cooler, drier, and sunnier Monday.
Coastal flooding remains a concern with morning high tides
This morning’s high tide peaked around 7.02′, which scraped minor coastal flooding thresholds. Expect additional rounds of minor to moderate salt water flooding around times of the morning’s high tide through Thanksgiving and the long weekend. High tide on Thanksgiving morning is forecast to peak around 7.5′, or moderate flood stage, around 7:43am. We should see similar results from Friday morning’s high tide which is predicted to peak around 8:34am. Minor coastal flooding is forecast for Saturday morning’s 9:29am high tide, while guidance indicates another round of flooding will be possible for Sunday morning’s 10:28am high tide. Stay tuned for Coastal Flood Advisories from the National Weather Service.
Cloud cover moving over the area tonight will make for a much warmer start to Tuesday than we saw on Monday, with lows only dipping into the mid to upper 40s. Wakeups will trend even warmer as we get into the rest of the week, with lows in the 50s becoming commonplace through the weekend.
Keep an eye out for a few showers during the day on Tuesday as a coastal trough develops. Otherwise, expect temperatures to top out in the low 60s under mostly cloudy skies.
There will be a risk for a little salt water encroaching on roads around Gadsden Creek (Hagood/Fishburne/Lockwood) around the 6:10am high tide, but more significant flooding is not expected as water levels are expected to peak just shy of the 7′ coastal flooding threshold in Charleston Harbor.
A Freeze Warning is in effect overnight as a killing freeze is likely going to end the growing season across the Lowcountry. While places near bodies of water such as Lake Moultrie and coastal areas should remain above freezing, the vast majority of us look to experience at least some duration of freezing temperatures, with the longest-duration freeze well inland. Protect plants, pets, pipes, and people tonight!
Temperatures will warm only to the mid-50s on Wednesday — perhaps a degree or two warmer than we saw today — but still well below normal for this point in November. We’ll dip back toward and likely below freezing in many spots again on Thanksgiving morning before high pressure slips offshore and return flow develops, helping temperatures to warm into the mid-60s with mostly sunny skies for much of the day. Friday morning will be considerably warmer ahead of a cold front that’ll swing through during the day. Said front will enhance cloud cover and help keep highs back into the low-to-mid 60s once again, a few clicks below normal but certainly not to the degree we experienced today and will experience again on Wednesday.
Travel safely (if you’re headed anywhere) and have a wonderful Thanksgiving holiday!
While many people in the Upper Midwest and along the West Coast will be dealing with nasty weather this Thanksgiving, we can be thankful for mostly quiet and comfortable conditions as we kick off the holidays.
